IPC: F16C43/04
Filed: 1979-02-23
Abstract: PURPOSE: To identify the face and the back of inner wheels of bearings having different external diameters between the face and the back with a simple structure and in a high speed by using parallel rails of different levels.  
     CONSTITUTION: When inner wheels a are sent horizontally onto a sending conveyor one by one, the inner wheels are sent out on different level parallel rails one by one with extended intervals because the next feed conveyor 9 to follow rotates in a comparatively high speed. In an inner wheel which points to the back, the lower right side is supported by the lower rail 15a surface of the rail 15. However, because the left side is not supported by the upper rail surface, it loses its balance, falls vertically from the left side and is put on a line feed part 17. On the other hand, the inner wheel a 1  which points to the face is supported by both the uppon and lower rails 15, if moves to a single rail 16, falls vertically from the right side and is put on the line feed part 17.

Title: Picture noise eliminating device
Inventor: SEKIZAWA HIDEKAZU
IPC: G06T5/30
Filed: 1984-02-10
Abstract: PURPOSE:To eliminate the picture noise while keeping a picture in high contrast by detecting the edge part of a picture to display the area near the edge in a high contrast with no averaging and performing the averaging at the area excepting the edge part to have a display in the form of smooth signals. CONSTITUTION:A separated luminance signal is supplied to an averaging circuit 4, and the original signal (x) is subtracted from the averaged signal (x') by a subtractor 5. This (x-x') shows a local variance factor of a picture, and the signal (x-x') is supplied to a deciding ROM6. Then the signal (x-x') is multiplied by the contents (k) of the ROM6 by a multiplier 7 and then added with the signal (x') by an adder 8. Thus the output (y) is equal to x'+k(x-x'), and y=x' is satisfied if the (k) is set at 0. Thus an averaged waveform is obtained. Then y=x is satisfied when the (k) is set at 1 to obtain a original sharp signal. Thus it is possible to control the averaging degree according to the local variance factor of a picture by changing the value of (k) in response to the ROM address.

Abstract: PURPOSE:To contrive endurance improvement of a probe and avoid part damage due to contact by hilling by the probe by providing a plunger, which receives spring force in the direction of Z-axis projecting in a Z-axis unit, on a probe edge part. CONSTITUTION:A measuring point height reading device 34 provided with the probe position adjustor 42 reads height of the Z-axis direction from a board reference plane of a measuring point on a mounting part input with an input device 32. A probe moving distance calculation means 36 is made to correspond to the height of its measuring point, calculates a moved distance from the reference position of a probe and a signal for moving the probe only up to its distance is given to an actuator 40 by means of an actuator drive signal production means. As a result, the probe is moved from the reference position and can be brought into contact with the measured point by light striking on the mounting part. Accordingly, even if the height of the measuring point is changed, a quantity of strokes of the probe can be similarly constant.

Title: Manufacture of positive electrode plate for lead-acid battery
Inventor: YAMANE YURIKO
IPC: H01M4/20
Filed: 1994-02-21
Abstract: PURPOSE:To provide a positive electrode plate of high chemical conversion efficiency for a lead-acid battery. CONSTITUTION:Lead powder 1 mainly comprising lead monoxide is coated with coating 2 which is not or hardly dissolved in sulfuric acid, but dissolved in lead hydroxide, and having pores 2a to which sulfuric acid is substantially impermeable, but to which water is permeable, so coated lead powder is formed. Active material paste formed by kneading the coated lead powder and mining with water is filled in a collector to manufacture a positive electrode plate for a non-chemically converted lead-acid battery. The lead powder coated with the coating will not react with sulfuric acid, so in an initial stage in formation of active material paste, almost 100% minium reacts with sulfuric acid to generate lead sulfate and lead dioxide. During kneading, water invading into the coating reacts with the lead powder coated with the coating to generate lead hydroxide. The coating is dissolved by this lead hydroxide to expose the lead powder, which then reacts with generated lead sulfate to be tribasic lead sulfate.

Filed: 1995-01-18
Abstract: PURPOSE: To prevent an adverse effect on precision cutting due to oscillation by screwing a feed nut and a ball screw in each other with a playwith a small clearance to absorb a run-out. CONSTITUTION: A work is diced by cutting the work by a rotary blade by way of moving a movable table repeatedly after finishing alignment, returning the movable tabel by a constant stroke and repeating this operation. At the time of movement of the movable table, as small clearances X, Y1 , Y2 are provided between the ball screw 3 and the feed nut 2, oscillation due to rotation of the ball screw 3 is not transmitted to the feed nut 2. Consequently, a chuck table does not oscillated, and it is possible to cut the work with precision.
